| frank26080115 | 0:bf7b9fba3924 | 21 | Purpose: |
| frank26080115 | 0:bf7b9fba3924 | 22 | This example describes how to write a simple USB Mass Storage application on LPC1768. |
| frank26080115 | 0:bf7b9fba3924 | 23 | Process: |
| frank26080115 | 0:bf7b9fba3924 | 24 | The MassStorage project is a Mass Storage simple demo run on LPC1768 |
| frank26080115 | 0:bf7b9fba3924 | 25 | Clock Settings: |
| frank26080115 | 0:bf7b9fba3924 | 26 | - XTAL = 12 MHz |
| frank26080115 | 0:bf7b9fba3924 | 27 | - PLL = 400 MHz |
| frank26080115 | 0:bf7b9fba3924 | 28 | - processor clock = CCLK = 100 MHz |
| frank26080115 | 0:bf7b9fba3924 | 29 | - USB clock = 48 MHz |
| frank26080115 | 0:bf7b9fba3924 | 30 | - CCLK / 4 clock = 25 MHz |
| frank26080115 | 0:bf7b9fba3924 | 31 | |
| frank26080115 | 0:bf7b9fba3924 | 32 | It demonstrates an USB Memory based on USB Mass Storage Class. |
| frank26080115 | 0:bf7b9fba3924 | 33 | The USB Memory is automatically recognized by the host PC |
| frank26080115 | 0:bf7b9fba3924 | 34 | running Windows which will load a generic Mass Storage driver. |
